California’s complex system of water rights took shape starting in the mid-1800s, when settlers saw the state’s water as abundant and free for the taking — a time when a Gold Rush prospector could stake claim to river flows simply by nailing a notice to a tree.
Today, California’s oldest and most senior water rights — called riparian and pre-1914 rights — have been passed along to thousands of agricultural landowners, irrigation districts and urban water suppliers that claim control of roughly one-third of the water that is diverted from the state’s rivers and streams.

Summer is approaching in California, and warmer temperatures have been melting the massive snowpack dumped on the state over the winter. Several swimmers and kayakers drowned this spring as rivers flooded and raged. The National Park Service took the rare step of closing much of Yosemite National Park’s scenic valley for several days to protect hikers and campers from floods. In April, California snowpack was at 237% of the average.

For decades, Western cities like Las Vegas and Tucson, Ariz., have embraced water conservation and recycling as a means of preparing for a multidecade drought like the one we’re experiencing. Despite our best efforts, our neighbors in Southern California, Northern Arizona and Utah have not always followed our lead. Cities like Phoenix, Los Angeles and St. George, Utah, have been allowed to grow at an explosive pace with little planning for where water would come from or how long the supply would last.

Helix Water District created its first demonstration landscape in July 2020 at the district’s administration office in La Mesa. The project beautifies the neighborhood and serves as an inspiration to install low-water-use landscaping.
Three unique water-wise gardens include a Mediterranean garden on University Avenue, a desert landscape on Lee Avenue, and a California native landscape at the main entrance on Quince Street. Each garden boasts an array of flowers, colors, and textures and is easily visible from the sidewalk. The plants in these gardens are adapted to San Diego’s climate, requiring half to a fifth of the water needed by a traditional lawn. The gardens, at 7811 University Avenue in La Mesa, are low maintenance and provide habitat for local wildlife.
The Helix Water District demonstration garden includes interactive elements such as descriptive signs with QR codes that visitors can scan to learn more about specific plants. Photo: Helix Water District
Plant markers display each plant’s name so visitors can write down their favorites and a QR code that can be scanned with a smartphone to access additional information such as light and water needs. Visitors can access hwd.fyi/get-inspired to download the garden plans, obtain plant lists, and view several resources available to help start their own garden.

The Vallecitos Water District developed its demonstration garden in 2010 with design plans from Palomar College Environmental Architecture and Design students. The project received support from local businesses, organizations, and District employees.
The garden showcases sustainable practices and includes a rainwater harvesting system that collects rain from the roof into three storage tanks with a combined 2,500-gallon capacity. This system reduces the reliance on potable water, and the captured rainwater is used for the prominent water features in the garden which run on solar power.
California-friendly plants are supported with plant-nurturing mulch, compost, and biosolid pellets made from recycled wastewater solids produced at a treatment plant partially owned by Vallecitos, the plants are bolstered with moisture and nutrients. This eliminates the need for chemical fertilizers.
The garden features a weather-based irrigation controller display, durable aluminum shade structures, dry riverbeds, artificial turf, micro-irrigation, and an artistic sculpture highlighting the value of water. A new private patio area has been added, and all pathways are now ADA-accessible.
Vallecitos’ sustainable demonstration garden has achieved recognition as a “Certified Wildlife Habitat” by the National Wildlife Federation in 2013 and has been acknowledged as a “Certified Earth Friendly Garden” by the Master Gardeners Association of San Diego County. In 2023, a Little Free Library was installed at the north end of the garden, stocked with garden books to inspire residents to adopt water-wise gardening practices. The garden is located at 201 Vallecitos De Oro, San Marcos.
The Water Conservation Garden

As California continues to experience swings from one weather extreme to another, a majority of residents say they are increasingly concerned about the state’s changing climate, and some worry that weather impacts could force them to move in the future.
Nearly 70% of registered voters say they expect that volatile fluctuations between severe drought and periods of heavy rain and snow — what some call weather whiplash — will become more common in the future due to climate change, according to a new UC Berkeley Institute of Governmental Studies poll co-sponsored by the Los Angeles Times.

This winter produced record snowfall in California, but a new study suggests the state should expect gradually declining snowpacks, even if punctuated with occasional epic snowfalls, in the future.
An analysis by Tamara Shulgina, Alexander Gershunov, and other climate scientists at UC San Diego’s Scripps Institution of Oceanography suggest that in the face of unabated global warming, the snowlines marking where rainfall turns to snow have been rising significantly over the past 70 years. Projections by the researchers suggest the trend will continue with snowlines rising hundreds of meters higher by the second half of this century.
California snowlines and lower-elevation ski resorts
In the high Southern Sierra Nevada range, for instance, snowlines are projected to rise by more than 500 meters (1,600 feet) and even more when the mountains get precipitation from atmospheric rivers, jets of water vapor that are becoming an increasingly potent source of the state’s water supply.
“In an average year, the snowpack will be increasingly confined to the peak of winter and to the highest elevations,” the study says.
Diminished snowfall is a consequence of a changing climate in which places like California will get an increasing portion of their winter precipitation as rain instead of snow. The authors said this study and related research suggest water resource managers will need to adapt to a feast-or-famine future. California’s water supply will arrive less through the gradual melt of mountain snowpack that gets the state through hot summers and more via bursts of rain and runoff delivered by atmospheric rivers, which are boosted by warming and are associated with higher snowlines than other storms.
Warmer summers
Such events will further complicate the balancing act between protecting people and infrastructure from winter flooding and ensuring enough water supply during warmer summers.
“This work adds insight into the climate change narrative of more rain and less snow,” said California Department of Water Resources Climatologist Mike Anderson. “DWR appreciates our partnership with Scripps to help water managers develop, refine, and implement adaptation efforts as the world continues to warm and climate change impacts are realized.”
The study, funded by the U.S. Bureau of Reclamation and the DWR, appears in the journal Climate Dynamics today.
“This is the longest and most detailed account of snow accumulation in California,” said Gershunov, “resolving individual storms over 70 years of observed weather combined with projections out to 2100.”
Climate change impacts to ski industry
The authors make note of what this could mean for ski resorts around the state if climate change progresses unabated. For example, Mammoth Mountain, at an elevation between 2,400 and 3,300 meters (7,900 – 11,000 feet), is projected to receive 28 percent less snowfall in the latter half of the century. Lower elevation ski resorts such as Palisades and Northstar, both near Lake Tahoe, span elevational ranges of around 1,900 and 2,700 meters (6,200 – 8,900 feet). They are projected to lose more than 70 percent of their snow accumulation in an average winter.
“Snowlines will keep lifting”
“Observations and future climate projections show that already rising snowlines will keep lifting,” said Gershunov. “Epic winters will still be possible, though, and unprecedented snowfalls will ironically become more likely due to wetter atmospheric rivers, but they will be increasingly confined to the peak of winter and to the highest elevations of the Southern Sierra Nevada.”
Study co-authors include Kristen Guirguis, Daniel Cayan, David Pierce, Michael Dettinger, and F. Martin Ralph of Scripps Oceanography, Benjamin Hatchett of the Desert Research Institute of Reno, Nev., Aneesh Subramanian of University of Colorado at Boulder, Steven Margulis and Yiwen Fang of UCLA, and Michael L. Anderson of the California Department of Water Resources.

“Thanks for Planting Me!” encourages more widespread adoption of sustainable landscapes to prepare the Southern California region for a hotter and drier climate.
The “Thanks for Planting Me!” summer campaign offers gratitude to the hundreds of thousands of San Diegans who have transformed their landscapes using low-water and native plants as part of a larger effort to use water more efficiently. Thanks for Planting Me! also is intended to show resident the WaterSmart advantages of embracing regenerative low-water landscapes as climate change stresses water supplies across the Southwest.
